speednob
This involved drawing as many penises as possible on a colleague's text book / excercise book / bag / homework diary / piece of artwork / photograph of dead relative etc. whilst their back was turned. It was perfected to 3 loops removing pen from paper only to draw in a "T" at the top. Twenty nobs in ten seconds was a skilled, but not uncommon occurrence.

Most effective when employed on a borrowed book, swiftly drawn while the classmate is looking away, or drawn across a piece of work that your classmate is about to hand in. There are no hard and fast rules for drawing the cock, but in most illustrations the cock is circumcised and the balls look like two croquet hoops.

A variation on speednob played at our school was known as a chunderbunder. Identical nob motif, but with one important and sometimes dangerous difference. The addition of an eye was accomplished by stabbing a biro as hard as possible into the excersise book, ideally penetrating 20 or more pages and providing a lasting reminder of the attack.
Victims had to be careful when defending to avoid a stab wound in the hand.

Why is it that all 'speednobs' are circumcised? In all my years of textbook observation never have I seen a phallus with a foreskin attached.
